I'm currently running the nightly from two days ago with the kernel that comes with CM10.1 and I can't seem to get wired or wireless tethering working at all. I used to use WiFi Tether for tethering on the stock 4.1.1 ROM and it worked fine back then, but using the same settings in CM10.1 doesn't work. I already tried a clean install of CM10.1 and re-downloaded/re-installed my apps as opposed to restoring them with Titanium Backup since people were saying that might cause issues. Tethering still didn't work. If I use WiFi Tether with the same settings that previously worked, it starts but says to check the log for errors. In the log it says it fails to configure the AP and fails to start AP. None of my devices see it. If I use the native wired tethering my data flickers on and off (3g/4g symbol fades in and out and my reception bars turn gray) and the computer it's plugged into gets no connection. Same with the native wireless tethering. Is anyone on CM10.1 and have tethering working? If so, what did you do to get it working?
